You need to run the msdash. It usually has a menu entry somewhere in the evox menu..
If not use a program like xbox explorer to run the xboxdash.xbe or msxboxdash.xbe file in c:\
(Xboxes are very customizeable as for the software load so the file name might be changed to something else, but these are the 2 most common ones.)
Also look over at the xbox-scene forums, they have tons of help for you.
